DEVICE FOR MEASURING PARAMETERS OF POROUS MATERIALS Russian patent published in 2017 - IPC G01N15/08 

FIELD: measurement equipment.

SUBSTANCE: parameter measuring device comprises a porosity materials fixed measuring chamber 1, the pump 7, through valve 8 connected with fixed measuring chamber 1, a computer 13 connected to the measuring chamber 1 fixed at one end and the other pump 7. Also, the device comprises a temperature sensor 15 associated with the computer 13, timer, built in the computer 13, the working chamber 2 connected with the atmosphere by measuring, connected to the pump control system 7 on the one hand and the computers 13 - on the other. The device also includes a pressure sensor 11 mounted on the stationary measuring chambers 1 and 2 the working chamber. When the device is further provided with movable measuring chambers 3 mounted with the pressure sensor 11 located inside the fixed measuring chambers 1 test material, the gas tank 17 and connected to the movable measuring chambers via a valve 16 3. Thus, the working chamber 2 is fitted inside a fixed measuring chamber 1 is movable, a temperature sensor 15 is mounted on the stationary measuring chamber 1, and a measurement control system is equipped with an automatic mechanism for moving the movable measuring chambers 3 fixed inside the measuring chamber 1.

EFFECT: improved accuracy.
